In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Example Input: Article: To the untrained eye it might seem like just a bit of a monkey trick. But when Milly the mandrill (, ) covers her face with her hand she is actually sending a serious message to her fellows: "Leave me alone!" Experts believe the 15-year-old mandrill invented the gesture to warn other monkeys at Colchester Zoo to give her some space. And, surprisingly, the signal has been picked by other members of the group, who use it when they too require _ . Biologist Mark Laidre believes the behavior is evidence of social culture among the mandrills. Importantly, the sign language is unlikely to have been influenced by human activities because mandrills do not copy humans. Mr. Laidre expects further research will uncover other monkeys using cultural gestures -- the ability to communicate with the hands in a meaningful way. "By covering their eyes with their hands, possibly conveyed to others that they wanted to be left alone and this message may have been respected as a 'do not disturb' sign," said Mr. Laidre. While the hand is in place, other monkeys are not likely to approach or touch the monkey. Those who rank lower in the social order also use the technique to avoid attacks from more powerful group members. As the discovery appears to be unique to Colchester Zoo, it suggests it is a local phenomenon that arose naturally in the community of 25 mandrills. Curator   Sarah Forsyth said: "We believe Milly made up the signal and over the past five years some of the younger mandrills have picked it up. We're not sure why she started doing it but it could be as simple as 'I can't see them, so they can't see me'. It really does show you how intelligent mandrills are." 
 Answer: A monkey invented a gesture.

Example Input: Article: If you hear the sound of a mobile phone beeping in a bag or pocket, you could think that someone has received a text message. Text messaging, or texting, is the art of sending a short, electronic message between two mobile phones. The users should pay a certain amount to send messages via SMS--- short message service. But in the last few years, with the development of smart phones, messaging in this way has been _  The rise of smart phones has seen an increase in the use of instant messaging apps. The apps offer a cheap alternative to traditional texts. Using wireless internet connections, people can send a number of messages to their friends at a very low cost. Unlike traditional mobile texts, the users usually only have to pay to download the app once, after which each message they send is free. Instant messaging apps have become popular all over the world. Hundreds of millions of people use the apps to chat with their friends. These apps allow people to send pictures messages for free---something which previously was quite costly. Many of these apps also allow users to have access to a huge range of colourful emotions, which can help people express their emotions. The research company Informa said that almost 19 billion messages were sent per day using chat apps last year, compared with 17.6 billion SMS texts. And it expects the chat app market to grow to 50 billion per day by 2015. So does this really mean the end of communicating by texting? Pamela Clark-Dickson from Informa doesn't think so. She says that there are a large number of people who use normal mobile phones, particularly in developing countries and prefer the SMS messaging tool. For the moment, these users still find that SMS is the best messaging experience for them. 
 Answer: It will cost the users some money for downloading the apps.
